    Patent number: 9413221
    Abstract: A power conversion unit includes power converters arranged sequentially to each other to convert input power that is provided at an input of the power conversion unit to output power. A set of first capacitors are arranged in series with each other and include, for each power converter, a first capacitor that is arranged in parallel with an associated power converter. Each first capacitor is also arranged to store a portion of the input power.
